Synthèse de nouveaux matériaux moléculaires par phosphonylation des dérivés aminés et étude de leurs propriétés électrochimiques et complexantes

Abstract

This work aims to study and electrochemical properties of complexometricphosphonic acid derivatives. We synthesized one member of the class α- aminophosphonics acids based on L leucine, the resulting products were characterized by chromatographic methods (TLC and column) and UV-Vis spectroscopy and IR. On the other hand we have studied properties of electrochemically complexometric acid 2,6-(dihydroxyphosphonyl) methyl, 4 methyl phenol(AMPDMP) towards cationsCu(II), Fe(III) andZr(VI) based different molar ratios are applying cyclic voltametry method. This study allowed use to conclude that AMPDMP has an affinity to form chelates with the cations studied and its complexes with Fe(III) andZr(VI) are polymerisable, which offers opportunities for their use in preparing modified electrodes and as corrosion inhibitors.
